A 3-D Look at Philippe Provided Clues of Transition into a Hurricane

07.10.2011
Tropical Storm Philippe took its time to strengthen into a hurricane because of wind shear problems.

The wind shear lessened, and Philippe became a hurricane today, after 12 days of moving across the Atlantic Ocean. NASA's TRMM satellite saw towering thunderstorms and intense rainfall within Philippe yesterday, which provided forecasters with a clue that the storm was strengthening. Philippe reached hurricane status this morning, Oct. 6, 2011.

Over two days, the Tropical Rainfall Measuring Mission (TRMM) satellite provided forecasters with cloud heights and rainfall rates occurring within Tropical Storm Philippe. TRMM is managed by both NASA and the Japanese Space Agency, JAXA.

The National Hurricane Center (NHC) upgraded Philippe to a hurricane at 1500 UTC (11 a.m. EDT) on Thursday, October 6 2011. Earlier TRMM Microwave Imager (TMI) data from October 6, 2011 at 0024 UTC (Oct. 5 at 8:24 p.m. EDT) showed that tropical storm Philippe's center of circulation had become better defined and an eyewall was forming. Microwave satellite imagery also shows an eye-like feature, while the visible imagery from NOAA's GOES satellite hints at the indication of an eye, although mostly covered with clouds.

On Oct. 6, Philippe's maximum sustained winds were near 80 mph (130 kmh). Philippe is a Category One hurricane on the Saffir-Simpson scale, but some weakening is forecast in the next two days. Philippe is located about 425 miles (680 km) southeast of Bermuda, near 27.8 North and 60.0 West. The hurricane is moving to the north-northeast near 9 mph (15 kmh) and is expected to move toward the northeast and speed up.

The TRMM satellite also had an excellent look at Philippe earlier on Wednesday, October 5, 2011 at 1752 UTC (1:52 p.m. EDT). TRMM's Precipitation Radar (PR) scanned directly over Philippe and revealed that Philippe had bands of intense rainfall that around the southeast side of the center of circulation.

A 3-D rendering of that TRMM PR data showed deep convective towers reached to heights of over 13km (~8 miles). Previous research from NASA scientists show that whenever these "hot towers" are spotted within a tropical cyclone, the storm typically intensifies within six hours, and Philippe became a hurricane today.

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...

Im Focus: Researchers develop method to transfer entire 2D circuits to any smooth surface

What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.

Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
